hi! it's the downstream oxygen sensor located right after the catalytic converter,,

P0161 is 02 sensor 2/2 heater performance.
there is no activity on sensor # 2
P0161 is a Lambda heater sensor malfunction (oxygen sensor) located in the front section of the exhaust system.
P0101 and P0161 are diagnostic trouble codes (DTCs) used in automotive diagnostics. P0101 refers to a problem with the Mass Air Flow (MAF) sensor, indicating a circuit range/performance issue, while P0161 pertains to the oxygen sensor circuit, specifically the heater circuit for the sensor in Bank 2. "PD" typically stands for "powertrain diagnostic" and may refer to the broader category of codes related to engine and transmission performance.
It is caused by Bank 2 Sensor 2 oxygen sensor failing.
